Yellow-green elongate chloroplasts. Eyespot present. Hypothecal, sausage-shaped nucleus. Reticulated thecal plates. Growth bands can be present. Trapezoidal shape of apical pore complex. Kofoidian plate formula is Po, X, 4ʹ, 3a, 7ʹʹ,?C,?S, 5ʹʹʹ, 2ʹʹʹʹ. Second anterior intercalary plate does not contact third anterior intercalary plate, as for the genus. First anterior intercalary plate quadrangular, second anterior intercalary plate hexagonal, and third anterior intercalary plate pentagonal. Two to three antapical spines present on 1ʹʹʹ, 5ʹʹʹ, 2ʹʹʹʹ. Cingular displacement 1.5–2.0. Sulcus widens towards the antapex. Based upon Biecheler (1952: 59–63).</p><p>Etymology: named for Berthe Biecheler (1901–1939) of the Station Biologique de l’Université de Montpellier à Sète, France; see Moestrup &amp; Enevoldsen (2019) for an account of her life and premature demise.
